You can
put this solution on YOUR website!Please help me determine which two equations represent parallel lines
y = -4x + 4
y = 4x + 4
y = 1/4x + 4
y = -4x + 5
FOR LINES TO BE PARALLEL ,THIR SLOPES SHOULD BE SAME.THAT IS WRITTEN IN STANDARD FORM OF
Y=MX+C.....M = SLOPE .. SHOULD BE SAME FOR BOTH LINES.
HERE IT IS TRUE FOR I AND IV LINES ,BOTH OF WHICH HAVE M=-4.HENCE THEY ARE THE PARALLEL LINES
